Compact 6.2mm DIN-rail module safeguarding 2-wire floating signal circuits. Engineered with a vertical disconnect knife, screw terminals, and SIL 3 rating.
The Phoenix Contact 2906781 (TTC-6P-1X2-F-M-24DC-UT-I) is a highly specialized modular unit from the TERMITRAB complete series. Designed to safeguard sensitive measurement and control technology, it consists of a protective plug and a base element. Featuring an integrated status indicator and a mechanical disconnect knife, this module is optimized for 2-wire floating signal circuits, such as 0(4) to 20 mA current loops. It supports indirect grounding via a gas discharge tube (GDT) and is fully HART-compatible. With its ultra-narrow 6.2 mm profile, standard M3 screw connection technology, and compliance with SIL 3 safety standards, it enables space-saving, highly reliable installation on standard NS 35/7.5 DIN rails.

Safeguards critical 4-20 mA floating signal circuits transmitting analog sensor data across harsh industrial petrochemical environments.
Prevents transient voltage spikes from damaging expensive PLCs and transmitters without interrupting the loop during routine testing and maintenance.
Used in tightly packed control panels where standard-sized module footprint constraints are a primary engineering concern.
The ultra-slim 6.2 mm footprint maximizes panel space while simultaneously delivering full 20 kA discharge protection and mechanical disconnect capabilities.
Protects remote field instruments and analog measurement probes from lightning-induced surges traveling along lengthy cable runs.
Provides indirect grounding via a gas discharge tube and built-in optical status indication to identify blown arresters instantly without external power.
